I'm getting the hang of photographing the planets with P1000 after some practice. Jupiter sets below the horizon too early these days, so I targeted Saturn and Mars. Using the Moon as the reference for the manual focus (actual setting seems to vary up to ten dial ticks by the daily conditions) and turning off the vibration reduction (better to let the tripod stabilize on its own), I was able to take several photos for processing. Discernible in the results are the prominent differences in the surface colours of Mars, as well as the Cassini Division on the rings of Saturn.

Mars as seen in 10-minute intervals starting from the midnight of August 1, 2018

Mars comes close to Earth every two years or so, but due to the elliptical orbit the closeness varies a lot. It came as close as 0.373 AU in 2003, while it was 0.674 AU away at its approach in 2012. The closest approaches happen every 15 or 17 years, and the latest one happened on 16:50 KST, July 31, 2018, at a distance of 0.385 AU. The next one will happen in 2035. Since this year's occurrence happened during the day, I did the next best thing and got my telescope set up that night to take a good look.

Unfortunately, Mars is experiencing a planet-level dust storm since early June and it has not subsided yet. A peek at the planet during last week's lunar eclipse indeed showed a mostly uniform orange disk, confirming my fears. I wasn't about to give up, so I got my Baader filter out and hoped for the best. Thankfully, the two-hour shooting session did not go to waste as the hours of post-processing finally revealed some discernible surface details, as you can see here.

You can even observe the planet visibly rotating in this video that incorporates all the photos I took. It's similar to what I made two years ago, but the continuous shooting made for a more fluid animation.

As I dropped by Gwangju to catch a movie (I'll be posting a comic tomorrow), the western sky was adorned with an alignment of some of the bright bodies of the solar system as seen from the Earth - the Moon, Mars, and Venus. The occurrence was relatively well-publicized, but I forgot to carry a dedicated camera tonight. Luckily, the telephoto lens of the iPhone 7 Plus pulled through and I was able to capture this sight over the neighbourhood just before Venus dropped behind the buildings.

A few hours after walking in the rain to see a movie yesterday, I was getting ready to sleep. Then I noticed that the sky was crystal clear, something I haven't seen in more than nearly two weeks (or three, in the night). Not to pass up this opportunity, I got my camera out. With so many stars visible, I wondered if the Milky Way Galaxy could be captured even with all the lights from the apartment buildings nearby.

After a few tries, it became clear that indeed it could be done, if somewhat faintly. Adjusting the levels, curves, and contrast brought out further details. Individual colour channels were untouched, yet the sky showed a very nice gradient. This may be an unintended affect of the light pollution near the horizon and I like how it turned out.

Mars rotates once every 24 hours and 37 minutes, so the look of the planet would visibly change as you keep an eye on the planet during the night. Owing to the fact that Mars is at its closest to Earth in more than ten years as I write this, this phenomenon had become relatively easy to photograph with my equipment. In fact, yesterday's post already illustrated this point.

However, I wanted to see if this could be made into an animation. So I managed to take photos of Mars in 30-minute intervals in the span of 4 hours. I wanted to stay up longer, but practical considerations like sleep and humidity prevailed. As you can see at the top, I ended up with a total of eight frames after post-processing nearly 3,000 burst mode photos taken with my iPhone 6S Plus mounted on the telescope. They were then put together into GIF animation that you see on the left.

The frames preserve the 2x digital zoom that I used while taking the photos because it allows you to discern the major features of Mars easier. The dark spot that sticks out on the right side of the planet in the first four frames is Syrtis Major Planum. The brighter area at the center of the planet in all the frames is Arabia Terra. Left side of the dark area just below the Arabia Terra is Meridiani Planum, where the Opportunity rover (MER-B) is currently operating (for more than 12 Earth years as of this writing). The dark area to the left of Arabia Terra visible on the last frame is Acidalia Planitia.
